Two homes: the account's workers.dev address (as lmjtfy began), and the custom domain whiskers.lmjtfy.fun, whose DNS record a Workers custom domain creates on deploy, as it does for lmjtfy.fun (~/lmjtfy/apps/lmjtfy/wrangler.toml). The link preview's absolute addresses come from SITE_ORIGIN, which the deploy names per home with --var SITE_ORIGIN:https://whiskers.lmjtfy.fun (or https://<name>.<account>.workers.dev), so this file carries no account name. The deployment procedure is kept by the owner, outside this repository.

The Worker and the link preview's PNG and MP4 (tools/build). Runs from this directory.

17command = "../tools/build"

wrangler rebuilds when these change; the build itself decides whether the preview is stale.

The link preview's files, built into public/preview/. The PNG is served by Cloudflare before this Worker runs. The MP4 is not: link-preview players (Discord, Twitter, iOS) fetch a video in byte ranges, which static assets do not answer, so /preview/loop.mp4 runs the Worker first (src/media.rs), which reads the file through the ASSETS binding and slices it. Both run the Worker first, so an old address (anything but SITE_ORIGIN's host) can send the link preview on to the canonical one (src/host.rs via site::host); the PNG is then passed to the assets by src/lib.rs. Anything else is the Worker's.

Where the site is, for the link preview's absolute addresses. wrangler dev --var SITE_ORIGIN:http://localhost:8788 previews itself.

Cloudflare's own record of what the Worker did. Invocation logs are off: they record each request, and this site's rule is that no visitor is written down by it. The Worker's own lines (src/log.rs) carry a route, a status and a time, and nothing else.
